Recently, We got a rumor from Some Xbox insiders that Ubisoft’s games could join Xbox Game Pass, similarly to how EA Play was giving earlier on Xbox with EA access. The Ubisoft+ subscription offers one plan, which includes all Ubisoft’s new and old games.
According to the Shpeshal Ed’s Discord chat screenshot, Ubisoft’s game may arrive at Game Pass by the end of 2021.
The Shpeshal Ed also mentioned that the price of the subscription with Ubisoft games included might not change. Although, they may choose to present separate services that consist of EA play and Ubisoft+ individually.
They also predict that everything up to Immortals Fenyx Rising could arrive in Game Pass.
This News is not confirmed, take this as a rumor or speculation until we get an official confirmation from Microsoft or Ubisoft.
